Hi all,
I just need some help in regards to the Tag Tree Browser. There are instances where I close the pop-up with this component, then Ignition gives me the error below. What is the best way to catch this? In my understanding this happens when the tag tree browser is in the middle of refreshing its contents and the closing action of the window are done simultaneously.
java.lang.NullPointerException
